Inverter DELTA VE/VL/VJ SERIES
VFD-VE Series
Features
This series adopts FOC (Field Oriented Control) which is a far more precise vector control algorithm. It can be used in both speed control and position control similar to a servo motor drive. The multi-function I/O terminal is expanded to meet users' various application needs. In addition, it is supplied with a Windows based PC software program for managing parameters and dynamic monitoring. It provides an excellent solution for load regulation. It can output 150% of rated torque at zero speed, and it can have "point to point" and relative distance control functions for position control, making it the best choice for challenging industrial control applications.

VFD-VJ Series
The Delta Hybrid Servo Drive VFD-VJ Series is designed with AC servo technology to drive hydraulic systems with perfect control of the drive, motor and hydraulic unit.
Specifications
- Field Oriented Control
- Suitable for both synchronous servo motors and asynchronous servo motors
- Built-in brake unit (up to 22kW)
- RS-485 communication interface (RJ-45) and standard MODBUS communication protocol
- Precise current detection for system protection with safety ensured
- New software for PC connection allows real time monitoring of AC motor drive status
Structure of a Hybrid Servo System
- When pressure and flow instructions are given to the injection molding machine, the Delta VFD-VJ series begins PID calculation simultaneously to attain the actual pressure and speed feedback data, and drive the servo motor and the hydraulic pump. The Delta VFD-VJ series offers you a system with fast response and high duplication accuracy.
